Question 1 of 5
A nurse is assessing a client's pulse oximetry on the surgical unit. As part of routine interventions, the nurse turns off the exam light over the client's bed. Which of the following best describes the rationale for this intervention?
Correct Answer: A
Rationale: When assessing a client's pulse oximetry values, the nurse should turn off any extra environmental lights that are unnecessary, including exam lights or over-bed lights. External light sources may cause falsely high oximetry values when the extra light interferes with the sensor of the oximeter, leading to inaccurate readings.
Choice B is incorrect because a bright light in the client's face would not directly affect the pulse oximetry values.
Choice C is incorrect as external light sources typically cause falsely high, not low, oximetry values.
Choice D is incorrect as the primary reason for turning off the light is to prevent falsely high readings, not solely for the client's comfort.
